Objective To analyze the correlation between cumulative fluid balance volume and increasing plasma volume and aggravated clinical congestion symptoms in patients with heart failure on admission for 1～7 d,and to explore the application value of cumulative fluid balance volume in predicting volume overload.Methods Using the convenience sampling method,235 heart failure patients hospitalized from October 2022 to February 2023 in a total of 3 tertiary hospitals in Nanjing,Lianyungang,Jiangsu Province,and Zhumadian,Henan Province,were selected and classified into an increasing/decreasing plasma volume group and an aggravated/alleviated clinical congestion symptoms group.General information,clinical characteristics,and 1～7 d cumulative fluid balance volume of the study subjects were collected to compare the differences in cumulative fluid balance volume between the 2 groups.Logistic regression was used to analyze the effect of cumulative fluid balance volume on plasma volume and clinical congestion symptoms.Receiver operating characteristic curves were used to analyze the optimal cutoff value of cumulative fluid balance volume for predicting increasing plasma volume and aggravated clinical congestion symptoms.Results Excluding 15 pat ients who were discharged early and 3 patients with inaccurate records of fluid intake and excretion,a total of 217 patients were included.The incidence of positive fluid balance was lowest on day 1,at 65.90%,with the smallest cumulative volume of(0.235±0.983)L;the highest incidence of positive balance occurred on day 6,at 75.58%,with the largest cumulative volume of(2.444±5.445)L.The cumulative fluid balance at 4～7 d in the increasing plasma volume group was higher than that in the decreasing plasma volume group,and the difference was statistically significant(P<0.05);the cumulative fluid balance at 4～7 d was an independent risk factor for plasma volume elevation,and a cumulative fluid balance of 2.308,3.361,3.518,and 3.702 L at 4～7 d was predictive of a plasma volume elevation,and areas under receiver operating characteristic curve were 0.686,0.721,0.647,and 0.766,respectively.The cumulative fluid balance for 4～7 d in the aggravated clinical congestion symptoms group was higher than that in the alleviated clinical congestion symptoms group,and the difference was statistically significant(P<0.05);the cumulative fluid balance for 4～7 d was an independent risk factor for the aggravated clinical congestion symptoms,and a cumulative fluid balance for 4～7 d of 2.574,3.383,4.995,and 4.235 L predicted aggravated clinical congestion symptoms,and area under receiver operating characteristic curve was 0.640,0.693,0.654,and 0.720,respectively.Conclusion The incidence of cumulative positive fluid balance in heart failure patients is high,and the amount of cumulative fluid balance can better predict the occurrence of volume overload,and the increase of plasma volume precedes the appearance of clinical congestion symptoms.It is suggested that heart failure patients with more than 3 d of cumulative positive balance should be closely monitored,and when the cumulative positive balance exceeds 2.308 L,measures should be taken in time to drain excessive fluid,so as to avoid the incidence of volume overload.

Background::Carotid intima-media thickness (IMT) and diameter, stiffness, and wave reflections, are independent and important clinical biomarkers and risk predictors for cardiovascular diseases. The purpose of the present study was to establish nationwide reference values of carotid properties for healthy Chinese adults and to explore potential clinical determinants.Methods::A total of 3053 healthy Han Chinese adults (1922 women) aged 18-79 years were enrolled at 28 collaborating tertiary centers throughout China between April 2021 and July 2022. The real-time tracking of common carotid artery walls was achieved by the radio frequency (RF) ultrasound system. The IMT, diameter, compliance coefficient, β stiffness, local pulse wave velocity (PWV), local systolic blood pressure, augmented pressure (AP), and augmentation index (AIx) were then automatically measured and reported. Data were stratified by age groups and sex. The relationships between age and carotid property parameters were analyzed by Jonckheere-Terpstra test and simple linear regressions. The major clinical determinants of carotid properties were identified by Pearson’s correlation, multiple linear regression, and analyses of covariance.Results::All the parameters of carotid properties demonstrated significantly age-related trajectories. Women showed thinner IMT, smaller carotid diameter, larger AP, and AIx than men. The β stiffness and PWV were significantly higher in men than women before forties, but the differences reversed after that. The increase rate of carotid IMT (5.5 μm/year in women and 5.8 μm/year in men) and diameter (0.03 mm/year in both men and women) were similar between men and women. For the stiffness and wave reflections, women showed significantly larger age-related variations than men as demonstrated by steeper regression slopes (all P for age by sex interaction <0.05). The blood pressures, body mass index (BMI), and triglyceride levels were identified as major clinical determinants of carotid properties with adjustment of age and sex. Conclusions::The age- and sex-specific reference values of carotid properties measured by RF ultrasound for healthy Chinese adults were established. The blood pressures, BMI, and triglyceride levels should be considered for clinical application of corresponding reference values.

Objective:To develop the Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with Inflammatory Bowel Disease (IBD), and test its reliability and validity.Methods:Guided by the theory of knowledge, attitude, and practice, a preliminary draft of the scale was formed through literature review, Delphi expert consultation, and pre-survey. From May to August 2022, convenience sampling was used to select 200 IBD patients who visited the Gastroenterology Clinic of three ClassⅢ Grade A comprehensive hospitals in Jiangsu Province as the research subject for a questionnaire survey. The critical ratio method, correlation analysis method, internal consistency method, commonality and factor loadings were used for item analysis of the scale. Exploratory factor analysis, content validity index, and internal consistency reliability were applied to test the reliability and validity of the scale.Results:A total of 200 questionnaires were distributed, and 181 valid questionnaires were collected, with an effective response rate of 90.50% (181/200). The Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with IBD included three dimensions of knowledge, attitude and practice, with a total of 21 items. The content validity index at the scale level was 0.917, and the content validity index at the item level ranged from 0.833 to 1.000. Exploratory factor analysis extracted three common factors, with a cumulative variance contribution rate of 74.197%. The Cronbach's α coefficient of the total scale was 0.951, and the coefficients of each dimension were 0.914 to 0.942. The test-retest reliability coefficient of the total scale was 0.918, and the test-retest reliability coefficients of each dimension ranged from 0.737 to 0.833.Conclusions:The Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with IBD has good reliability and validity, which can help medical and nursing staff evaluate patients' understanding and acceptance of microbial transplantation, so as to provide a basis for personalized communication in shared decision making between doctors and patients.

Objective:To explore the barriers and facilitators of exercise rehabilitation in patients with atrial fibrillation (AF) after radiofrequency ablation.Methods:From March to August 2022, 285 patients with atrial fibrillation who underwent radiofrequency ablation within three months were recruited from the "Cloud Ward" of the Department of Cardiovascular of the First Affiliated Hospital with Nanjing Medical University by convenience sampling. The Cardiac Rehabilitation Barriers Scale (CRBS) and the Self-efficacy for Exercise Scale (SEE) were used to evaluate the barriers and self-efficacy of patients participating in exercise rehabilitation, respectively. Among them, 22 patients were subjected to semi-structured interviews to extract themes.Results:Among 285 patients with atrial fibrillation, 202 (70.88%) participated in exercise rehabilitation programs. Work/time conflicts, lack of cardiac rehabilitation knowledge, and health/physical function limitations affected the participation of patients in exercise rehabilitation ( P<0.05). Qualitative research extracted three themes that affected the patient's exercise rehabilitation, including capability, opportunity, and motivation. Conclusions:The participation of atrial fibrillation patients in exercise rehabilitation is influenced by multiple factors such as family responsibility, capability, motivation, and opportunity. Medical and nursing staff should comprehensively consider the above factors, develop targeted interventions from all aspects and multiple angles, so as to effectively improve the participation of patients in exercise rehabilitation.

Objective:To analyze the selection of outcome indicators for randomized controlled trials (RCT) on exercise rehabilitation in patients with atrial fibrillation (AF), promote the construction of the core outcome set and provide reference for the research design of subsequent RCT.Methods:The RCT literature related to exercise rehabilitation of patients with atrial fibrillation was systematically searched from CNKI, Wanfang, VIP, PubMed, Web of Science, Embase and Cochrane Library databases, and the search period was from establishment of the databases until July 31, 2023. After literature screening, Cochrane Risk of Bias Assessment Tool was used for quality evaluation, information extraction, classification of outcome indicators, frequency of use statistics, analysis and extraction of current shortcomings in the selection of outcome indicators, and corresponding suggestions were proposed.Results:A total of 32 articles were included, and 19 RCT were evaluated twice for outcome measures. The number of outcome measures ranged from 2 to 17, with 10 RCT setting outcome measures according to primary and secondary criteria and 6 RCT setting safety outcome measures. A total of 96 outcome indicators were extracted in this study, total 266 frequency, which could be divided into 4 categories, such as safety evaluation (18 times), clinical response (75 times), patient-reported outcomes (68 times) and laboratory and other examination (105 times) .Conclusions:Existing RCT outcome indicators of exercise rehabilitation in patients with atrial fibrillation emphasize the changes in subjective feelings and objective indicators of individuals, covering four aspects such as the physical condition, exercise ability, quality of life and psychological status of individuals. However, there is a lack of uniform standards and the safety evaluation indicators are fewer. The categories of exercise rehabilitation indicators for atrial fibrillation patients extracted in this paper can provide a reference for the design of future RCT studies and promote the generation of higher quality evidence-based medical evidence.

Objective To construct a rehabilitation nursing program for stroke patients based on the international classification of functioning, disability and health (ICF). Methods The relevant domestic and foreign literatures were systematically searched, and a draft of the rehabilitation nursing program for stroke patients based on the 17 functional items in the four dimensions of ICF functional evaluation was constructed. The Delphi method was used to consult experts to further improve the program. Results A total of 16 experts completed two rounds of expert consultation. The expert authority coefficients of the first and second rounds of consultation were 0.897 and 0.897, respectively, with coefficient of variations ranging from 0.05 to 0.27 and 0.05 to 0.19, respectively. The Kendall's W coefficients were 0.384 and 0.452 (χ²=104.375, 122.831, P < 0.001), respectively. In the final rehabilitation nursing program for stroke patients, there were four first-level indicators (functional domains), 17 second-level indicators (intervention contents), and 73 third-level indicators (specific measures). Conclusion The rehabilitation nursing program for stroke patients based on ICF is scientific and reliable, and may provide theoretical support and practical guidance for the rehabilitation nursing of clinical stroke patients.

Objective:To retrieve and analyze the evidence related to perioperative blood glucose management in patients with coronary heart disease (CHD) complicated by diabetes undergoing percutaneous coronary intervention (PCI) , and provide clinical guidance for glucose management.Methods:Systematic searches were conducted on domestic and international guideline websites, evidence-based databases, primary research databases, and related association websites for evidence concerning perioperative blood glucose management for this patient group. The search included clinical decisions, guidelines, expert consensus, evidence summaries, and systematic reviews, covering the time span from database inception to February 2022. Two evidence-trained researchers independently conducted literature quality assessments and evidence extraction, with disputes resolved by a third party.Results:Eighteen articles were included: one clinical decision, nine guidelines, and eight expert consensuses. The findings were summarized into eight aspects: team formation and training, admission assessment and treatment, blood glucose control targets, preoperative glucose management, intraoperative glucose management, postoperative glucose management, perioperative abnormal glucose management, and discharge management, totaling 35 evidence points.Conclusions:This study consolidates evidence related to perioperative blood glucose management for patients with CHD complicated by diabetes undergoing PCI. However, during the evidence translation and application process, conditions of the application site, medical resources, and patient preferences should be fully considered. After assessing the feasibility and applicability of the evidence, a personalized blood glucose management plan should be developed for the patient, aiming to improve blood glucose levels and prognosis.

Objective:To explore the influence of character strengths of nursing interns on work engagement, and the chain intermediary effect of perceived social support and professional identity.Methods:From November to December 2021, 551 nursing interns from 4 ClassⅢ Grade A hospitals in Nanjing were selected by convenient sampling. The General Information Questionnaire, Three-dimensional Inventory of Character Strengths (TICS) , Perceived Social Support Scale (PSSS) , Professional Identity Scale (PIS) and Utrecht Work Engagement Scale (UWES) were used to investigate nursing students. A total of 551 questionnaires were distributed and 511 valid questionnaires were recovered, with a valid recovery rate of 92.74% (511/551) .Results:Among 511 nursing interns, the overall scores of character strength, perceived social support, professional identity and work engagement were higher than the theoretical median. Pearson correlation analysis showed that there were positive correlations between character strength, perceived social support, professional identity and work engagement ( r=0.293-0.666, P<0.01) . The intermediary effect analysis showed that character strength could positively predict work engagement, and the direct effect was 0.271, accounting for 48.57% of the total effect. The intermediary effect of perceived social support between character strength and work engagement was significant, and the indirect effect was 0.147, accounting for 26.34% of the total effect. The intermediary effect of professional identity between character strength and work engagement was significant, and the indirect effect was 0.048, accounting for 8.60% of the total effect. Perceived social support and professional identity had a significant chain intermediary effect between character strength and work engagement, with an indirect effect of 0.092, accounting for 16.49% of the total effect. The total indirect effect of character strength on work engagement was 0.287, accounting for 51.43% of the total effect. Conclusions:The chain intermediary effect of perceived social support and professional identity on the character strengths and work engagement of nursing interns is established. Helping nursing interns identify and use their character strengths, paying attention to the care measures for nursing interns, and scientifically constructing the professional identity training system can enhance the work input of nursing interns.

Objective:To explore the status and influencing factors of participation in cardiac rehabilitation of cardiovascular nurses.Methods:This is a cross-sectional study. From January to February 2022, a total of 3 047 cardiovascular nurses in members of China Cardiovascular Health Alliance were selected as research objects by convenience sampling method. General data questionnaire and Cardiovascular Nurses Participated in the Cardiac Rehabilitation Questionnaire (CNPCRQ) were used to investigate cardiovascular nurses. Multiple linear regression analysis was used to investigate the influencing factors of participation in cardiac rehabilitation of cardiovascular nurses. A total of 3 047 questionnaires were distributed in this study, and 2 704 valid questionnaires were effectively received, with an effective recovery rate of 88.74%.Results:The total score of CNPCRQ of cardiovascular nurses was (93.23±31.58), which was at a moderate level. Multiple linear regression analysis results showed that age, education, professional title, hospital location, hospital level, position type and hospital type were the influencing factors of participation in cardiac rehabilitation of cardiovascular nurses.Conclusions:The status of participation in cardiac rehabilitation of cardiovascular nurses in China needs to be improved. Role and job content of cardiovascular nurses should be further clarified, and cardiac rehabilitation knowledge and skills training should be strengthened in the future, so as to promote the profession development of cardiac rehabilitation and improve patients' health outcomes.

Objective:To implement scoping review of the quality evaluation tool for mobile medical applications (mHealth APP) based on the perspective of health promotion, so as to provide reference for the development or introduction of tools suitable for China and provide inspiration for conducting high quality mHealth APP electronic health intervention research.Methods:Following the method of scoping review, mHealth APP quality evaluation tool development and validation articles published from January 2008 to February 2022 were systematically searched in Cochrane Library, PubMed, EMbase, Institute for Scientific Information (ISI) Web of Science, SCOPUS, CINAHL, PsyINFO, China National Knowledge Infrastructure, VIP, WanFang Data and China Biomedical Literature Database. This study extracted the basic information of the tool and used topic analysis to summarize and integrate the content of the tool items.Results:A total of 27 studies were included, involving 14 mHealth APP quality evaluation tools. The theme analysis process of evaluating the content of items generated a total of 300 primary codes, which were classified into four themes, including software attributes, medical science, behavioral science, and user experience.Conclusions:As a cross disciplinary product, the mHealth app faces multiple challenges in terms of quality. At present, the focus of existing quality evaluation tools varies, among which scientific evaluation originates from the special positioning of mHealth APP and needs to be taken seriously. Different evaluation perspectives may be potential factors that affect the quality evaluation results, and as a key link, users' needs need to be further focused and explored.
